Verdict
The clearest difference is rating: Voidol at 2.3 against SAY's 1.1. SAY's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, ratings volume, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Voidol sells 10 one-off in-app purchases. SAY asks for nothing beyond the download.
Voidol holds the better App Store score, 2.3 against 1.1. Both are backed by a comparable volume of ratings — 10 and 7 respectively. Written reviews complicate that: 18% of Voidol's written reviews are positive against 52% of SAY's, so the app with the better star average is not the one people write more warmly about.
Voidol ships an update every 3 months, SAY every 6 weeks. Both last shipped on November 3, 2026.
